た。"Prior Art" In recent years, in order to preserve the quality of groundwater, it has become common to regularly sample groundwater from deep wells and conduct water quality surveys. At this time, it is necessary to pump up the groundwater in the deep well, but conventionally, when pumping up the groundwater in the deep well, a deep well pump,

ないという問題がある。"Problems to be Solved by the Invention" By the way, in the case of observation wells, etc., the diameter of the well casing is small (for example, about 50 mm), so the above conventional deep well pump cannot be inserted into the deep well. In addition, in the above-mentioned conventional air lift pump, the compressed air supplied to the air lift pump violently agitates the groundwater in the deep well, resulting in impurities being mixed into the pumped groundwater. However, there is a problem that accurate groundwater composition cannot be obtained. Furthermore, when a container is lowered into a deep well to collect groundwater, only the accumulated water in the well is pumped up, and there is a problem in that it is not possible to ascertain the exact state of the groundwater at the time of measurement. .
このように、上記いずれの場合においても本質

す。"Operation" In the deep well pumping device of the present invention, compressed gas is supplied from the blowhole to the inside of the pumping pipe via the gas supply pipe, and a vacuum device connected to the pumping pipe is operated to supply the compressed gas to the inside of the pumping pipe. In combination with the suction power of a vacuum device, fluids such as groundwater and sediment are sucked up from deep wells, while fluids are alternately introduced into a pair of tanks using a water sampling switching valve mechanism. In this way, when one tank is full of fluid, switch to introduce fluid into the other tank, close the exhaust valve and start the sampling tank in the tank that is filled with fluid. Open the intake valve and take out the fluid in the tank to the outside.

る。 In order to pump water or pump mud at a high head (when the depth H from the ground surface GL to the groundwater level WL exceeds 10 m) using the deep well pumping device configured as described above, first, While inserting the lift pipe 1 into the casing 3, one of the switching valves 7 and 8 is opened and the other is closed (for example, the switching valve 7 is opened and the switching valve 8 is closed), In this state, compressed air is sent into the gas supply pipe 4 from the gas supply source 5, and the vacuum device 20 is operated. As a result, the compressed air in the gas supply pipe 4 is ejected from the blowhole 4a into the lift pipe 1, mixes with the water accumulated in the lift pipe 1, and pushes it up, creating a so-called air lift effect. Since the action of creating a negative pressure inside the pipe 1 works, the accumulated water in the well rises inside the pumping pipe 1 due to the combination of these two actions, and is stored in the vacuum tank 9 via the branch pipe 6 and the switching valve 7. be done. In this case, the compressed air in the gas supply pipe 4 is transferred from the jet nozzle 4a to the pumping pipe 1.
Since the water is ejected into the well, there is no need to violently agitate the inside of the well. Further, the gas A separated from the groundwater contained in the vacuum tank 9 is discharged from the vacuum device 20 through the exhaust valve 17 and the vacuum extraction pipe 19.

The switching valve 8 is opened and the switching valve 7 is closed to guide groundwater to the other vacuum tank 10. In this way, when the accumulated water in the deep well casing 3 is pumped up by alternately repeating the opening and closing operations of each of the switching valves 7 and 8, the accumulated water in the well is automatically replaced with underground percolation water. By sampling at the stage when it has replaced underground seepage water, the state of the groundwater at the time of sampling can be investigated. In addition, when the head is low (H < approx. 10m
(time), water can be pumped simply by directing the vacuum device 20 without supplying compressed air from the gas supply source 5. In addition, by changing the insertion depth of the lift pipe 1, the blowhole 4a of the gas supply pipe 4 can be
Because the relationship between the position of WL and the groundwater level changes,
Pumping head and pumping amount can be easily adjusted. In addition, the groundwater level can be measured by inserting the pumping pipe 1 into the deep well casing 3 with only the vacuum device 20 in operation and detecting water landing in the pumping pipe 1 by a change in the vacuum gauge. .

効果を有する。"Effects of the Invention" A pumping pipe that is inserted into a well to pump up fluids such as liquid or slurry in the well, and a pipe for spouting gas into the pumping pipe from a blowhole installed at the bottom of the pumping pipe. A gas supply pipe, a vacuum device connected to the lift pipe and for creating a negative pressure inside the lift pipe, and a gas provided between the lift pipe and the vacuum device and pumped up by the lift pipe. and a water sampling device for collecting fluid, the water sampling device comprising an integrated tank for storing the fluid pumped up by the pumping pipe, and a tank for storing the fluid drawn up by the water pump, and a tank for alternately collecting the fluid in each tank. A water sampling switching valve mechanism to be introduced, a sampling pot provided in each of the above tanks and for taking out the fluid in the tank, and a sampling pot which is installed in each of the above tanks and is installed in the tank when taking out the fluid from each sampling pot. It consists of an intake valve that supplies gas to the tank, and an exhaust valve that is installed in the tank and discharges the gas to the vacuum device, so compressed air is pumped from the blowhole through the gas supply pipe. In addition to supplying water to the inside of the pipe, a vacuum device connected to the pumping pipe is operated to suck up fluids such as groundwater and sediment from inside the deep well using a combination of compressed gas and the suction force of the vacuum device. A water sampling switching valve mechanism is used to alternately introduce fluid into a pair of tanks, and when one tank is full of fluid, the switch is switched to introduce fluid into the other tank. In the tank filled with fluid, the exhaust valve is closed and the sampling tank and intake valve are opened to take out the fluid in the tank to the outside. Groundwater, sediment, and other fluids can be pumped up continuously and quantitatively from the well, and the water stagnant in the well is automatically replaced with underground water, making it easy to collect groundwater at the time of pumping. By sampling using a water sampling device, samples can be taken continuously and at any time during pumping work, and the original condition of groundwater can be ascertained. Further, it has excellent effects such as being able to easily adjust the lift height and the amount of water lifted by simply changing the insertion depth of the lift pipe.
